Up on Madison Down on 75th (en Inglés) - Jon F. Rice

Excerpt:

About 4:30 a.m., police pulled up to the apartment at 2337 W. Monroe. Eight went to the front door of the first-floor apartment, and six went to the back. The block was sealed off by other police as the fourteen officers climbed the stairs. 

The woman who lived upstairs from Fred heard a knock at the front door below her. She said she heard someone say, "Open up, police." There was a pause-then all hell broke loose.

A shot exploded at the front door, followed by machine gunfire and bursts from other guns. As the shooting began in the front, it was followed by shooting in the rear of the apartment. For a full ten minutes, a barrage of fire was heard-screams and more fire.

What happened can, for the most part, be pieced together from the physical evidence left.
